:lECIEICATION forming part of Letters Patent No. 315,875, dated April 14, 1885.

Application led November 6, 1884. (No model.) Patented in Belgium April 15, 1884, No. 64.665; in AnstriaHnngary April 22, 1584, No.7,344 and No. 17,623, and' in France July 15, 1884, No. 161,271.

.'Z'o all whom, t may concern.'

Be it known that I, FRANZ WLACH, a citizen of Austria-Hungary, residing at Vienna, in the Province of Lower Austria and Empire of Austria Hungary, have invented new and useful Improvements in Lanterns, (for which I have obtained patents in Austria, No. 7,344, bearing date April 22, 1884; in Hungary, No. 17 ,628, bearing date April 22, 1881; in Belgium, No. 64,665, bearing date April 15,1881, andin France, No.161,271, bearing date July 15, 1884,) of which the following is a specification.

This invention relates to a lantern which can be used in the open air and which can be swung about without danger that the iiame may be extinguished.

The peculiar and novel construction of the parts of my lantern whereby the above results are obtained is pointed out in the following specification and claims and illustrated in the accompanying drawings, in which- Figure 1 represents a vertical section of the lantern complete. Fig. 2 is a side view of the burner detached. Fig. 3 is a transverse section of the same in the planea: Fig. 4. Fig. 4 is a plan or top View.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a 3o jacket oi cylindrical or any other suitable form. In the interior of this j aoket, at a short distance above its bottom edge, is secured a concave plate, b, and the rim c beneath this plate is perforated with a large number of holes. N ear the top of the jacket A is a circular shoulder, d, and beneath this shoulder is situated an annular foraminous plate, e.

Bis the oil-fountain. From this fountain projects a foraminous flange, f, which, when said fountain is placed into the jacket A, bears upon the shoulder d. The bottom part of the fountain is contracted,and extends through an opening in the concave plate b of the jacket, leaving an annular air-passage, g, the object of which is hereinafter more fully explained.

The oil-fountain is retained upon the shoulder d by a cap, C, which fits into the top of the jacket A,and is held in position by one or more spring-latches, 7i.

D is the wick-tube, which is secured in the fountain B by a screw-thread or other suitable means, and on this wick-tube is placed the cone E. This cone is composed of two side plates, z-, and two base-strips, j, and it is attached to the burner by means of sleeve .7a. (Best seen iu Figs. 2and 3.) The side plates, i, are provided with openings Z, and they come close together at the top, so that a transverse section of -my cone has some resemblance to an ordinary burnercone, as shown in Fig. 3; but by referring to Fig. 4 it will be seen that an open-air passage, m, is left between the side plates, c', in the direction transversely to the base-strips j, and thatsaid passageis gradually increasing in width from the top downward, and by the openings Z air is admitted to the flame in a direction at right angles to the air-passage m above named. At the same time a free supply of air reaches the lamerfroin below, such air being admitted through the holes in the bottom part of the jacket A, whence it passes through the air-passage g into the space surrounding the oil-fountain and thence through the foraminous plates e f and the cap Cinto the space beneath the cone E. It will be seen from this description that the air which is admitted through the bottom part of the jacket in its passage to the burner circulates around the oil-fountain so as to keep the same cool and to prevent the formation of gases, and at the same time the atmospheric air passes beneath the cone E not only from below, but also through the air-passage m and the openings Z, and a bright dame is obtained without the use of a chimney. The fora-minous plates ef are .used to prevent the flame from being extinguished by wind or by rapid movements of the lantern.

With the jacket A is connected the guardframe F, which is made of wire or other suitable material, and which consists, essentially, of the bottom plate, n, the top plate, o, and the wires p, the bottom plate, n, being connected to the jacket A by a hinge-joint, q, so that the guard-frame can be swung back to give access to the lamp.

Between the plates n and o is secured the globe G, or instead of a globe a series of de- IOO o, supports the chimney H, which consists of the spout r, the'bell s, and the hood t, the bell and the hood being'supported by strips u,

which are fastened on the interior ofthe spout 1^. The bottom part of the bell overlaps the mouth of the spout,and the hood overlaps the top part of the bell, so that the products of combustion can escape freely from the inte# rior of the lantern,while the flame is protected against the influence of wind.

I is the handle. l

My lantern can be used with advantage in the service of 'railways and fire-departments, and generally in the open air.

I am aware that a lamp-burner has been composed of side plates having their upper edges adjacent to and above the wick-tube, so that a transverse airpassage is created to admit air to the base and sides of the flame and around the wick-tube.V

I am also aware that a lantern has been constructed in which breaks or deiiectors are arranged in the air passages and chambers used to conduct air to the burners from the base of the lantern. Such features, therefore, I do not claim.

What I claim as new, and desire to secure by Letters Patent, is-

I. In alantern,the combination ofthejacket A, having the bottom plate, b, having a central opening, the oil-fountain B, suspended in lthe jacket and having its base arranged in the opening of the bottom plate to form the annular air-passage g, the upper and lower annular foraminous plates, fand e, .interposedbetween the jacket and the fountain,and a burn-l .er,' substantially as described.-

2. In a lantern, the combination of a shell. A, having an apertured bottom plate, b, and provided adjacent to its upper edge with a shoulder, an annular forarninous plate, e, secured to the shell below the shoulder, and an oil-fountain having an attached annular foraminousl plate, f, suspending the fountain from the shoulder, said fountain and apertured bottom plate being arranged to form the air-passage g, substantially as described.

, 3. The combination, substantially as hereinbefore described, with the fountain B and the jacket A,of the air-passage g,the air-space surrounding the fountain, the foraminous plates e f, the wick-tube D, the side plates, i,

.openings Z, and air-passage m.

4. The combination, with the wick-tube D, of the cone consisting of the sleeve 7c, the basestrips j j, connected with the sleeve, and the side plates, t i, provided with the openings l I, and having their upper ends arranged adjacent to each other and constituting between them the vfree air-passage m, transversely to the -basestrips, substantially as shown and described. In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
